' Specification of Letters Patent.

Application filed May 24, 1916. Serial No. 99,806.,

To all 'wkom it may concern:

Be it known that I, FRANK J. DUNLEAVY, a citizen of the United States, residing at San Francisco, in the county of San Francisco-and State of California, have invented certain new and useful Improvements in Buckles, of which the following is a-specification.

My invention relates to a buckle and its main object is to provide a novel and efiicient form of connecting article of this nature which may be manufactured at exceptionally low cost and be adapted for manufacture in one piece.

nection with accompanying drawings illustrating one preferred embodiment.

. In said drawings Figure 1 is a fragmentary view in side elevation, illustrating my improved buckle in connection with a belt;

Fig. 2 is a bottom or inverted plan view of the parts of Fig. 1;

Fig. 3 is a cross sectional view on the line 3-.3 of Fig. 1, and

Fig. 4 is a detailview of a modified form of clamping arm.

Referring specifically to the drawings, wherein like reference characters designate like or similar parts, the improved buckle is shown at A as connecting end portions 5 and 6 of a belt B together. While I have shown and will describe the invention in connection with a belt, it is not to be understood that a limitation to use in connection with a belt is to be imported, since the article is ca able of use as a buckle generally and additionally for instance in connection with straps, saddlery, and regardless of the specific material from which same is condle bridge 7, a binder or clamp arm 8 extending parallel thereto but spaced therefrom and connected thereto at one end by means of a connector section 9. Connected with the opposite end of the bridge 9 is a connecting section 10 for a clamp or binder arm 11 similar to the arm 8 and being parallel thereto and to the bridge 7.

The end portion 5 of the belt is in the form of a loop as seen in Figs. 2 and 5 anchored or fastened to the bridge 7 The free end of the belt is insertible into the spaces intermediate the arms 8 and 11 and the straddle bridge, adapted to seat on the portion 5 and be engageable with the inner edges 12 and 13 of the arms 8 and 11 respectively. The free ends of the arms 8 and 11 terminate in lugs 14 and 15, respectively, opposite the portions 10 and 9 and spaced therefrom to provide insert openings 16 and 17.

when the belt is unbuckled. the end 5 is merely connected to the straddle bridge and end 6 is free. In order to attach the end 6 or buckle it, it is passed through the openings 16 and 17while at an angle to the other section so as to enter the spaces intermediate the arms 8 and 11 and the straddle bridgebind with the portion 5 and with the edges 12 and 13 so that tension of the belt will maintain the portion6 buckled to the portion 5. Straddle bridge 7 is so arranged that when the portion 6 is buckled, it will I not be straight, so that the binding action with the edges 12 and 13 will be increased. To unbuckle the portion 6 it is merely necessary to relieve the belt of tension and then turn the portion 6 at an angle to the portion 5 so that it may detach by movement through the openings 16 and 17. It will be realized that the lugs 14 and 15 overlap the portions 6 adjacent the openings 16 and 17 so as to prevent displacement or detachment of the portion 6.

In some instancesdt will be desired to serrate the edges 12 and 13' to increase the binding action on the belt. Such a serrated edge is shown at 18 on the binder arm 8 in Fig. 4.

Since merely one embodiment of the invention has been illustreted and described to set forth its principle, it is to be understood thet changes in the detnils of con struction may be resorted to within the spirit and scope of the invention. 1 claim.- A buckle including e straddle her, clamp ing arms disposed on opposite sides of said bar and connected to the opposite ends thereof, said clamping arms having their nd'ncent longltudinel margins beveled to provide r eeenee downwardly end forwerdly directed cutting edges, said cutting edges being disposed snbstentielly in elinement with the upper edge of said straddle her end serreted to pro- 115 wide penetrating teeth.
